A cDNA encoding rat aromaticl-amino acid decarboxylase (AADC) was successfully expressed inEscherichia coliusing a T7 RNA polymerase expression system. Two types of expression vectors were tested and revealed to be equivalent to produce AADC. The enzyme was purified in both cases. The ratio of recovery of the pure active recombinant protein was better when the purification of the protein was made...
La sequence de l'ADN codant la decarboxylase des acides amines aromatiques de la serie L a a ete inseree dans le vecteur pMAL-c2 permettant l'expression de cette proteine chez Escherichia coli (E. coli). Apres purification et traitement de la proteine de fusion par le facteur Xa (FXa), une seule forme active de l'enzyme, resistante au FXa, a ete isolee. La proteine possede des constantes cinetiques...
